Discover Networks of Social Influence



build Deeper connection with your audience

Graphika™ offers the most powerful way of identifying and acting upon key influencers in the global social media sphere.

Graphika’s pioneering algorithm maps networks of interactions and relationships—not simply text content—for both social media leaders as well as their influenceable micro-segments or “neighborhoods.”  For clients in the Media, Healthcare, News, and other industries, Graphika provides the context needed to make strategic business decisions and create meaningful interaction with audiences. 

Because it is based on what people do, not just what they say, Graphika’s platform works across every language group, geographic region, vertical market, and business priority. Social networks are built on human relationships. The conversations that take place online are not merely streams of text flowing through time—they are interactions between individuals within coherent communities.  It is critical to understand how people are connected in order to effectively join and influence the conversation.
